Hello there,
I am not quite sure how to interpret the output of Rprof (in the following the
output I was staring at). I was poking around the web a little bit for
documentation but without much success. I guess if I want to figure out what
takes so long in my code the 2nd table $by.total and the total.pct column (pct
= percent) is the most helpful. What does it mean that [ or [.data.frame is
taking so much time, and is there something I could do to improve the situation.
Thanks,
